To play along on Work-in-Progress Wednesday, make your blog post for Wednesday be about something you're working on - some type of craft, renovation project, landscaping, even that novel you're writing. You can play along even if it’s not Wednesday; I leave each WIP up until the following week. Copy the code below Rosie's picture and paste it into your blog post so that others can follow too, and see the rest of the projects that are posted here.
